i placed a pill in 90 degree white vinegar.
after 30 minutes, about 1/32" had disolved and the tablet was still firm. i checked again after an hour
and itt was at 50%. also, there were a lot of large particles floating on the surface and some in suspension. the greens seemed to loosen up first.
this multivitamin is priced well and has a very good list of ingredients, but i will go with a liquid formula foe better absorption.
